Abstract
The aim of the study is to reveal the features of the subsequent reforestation of conifers on the logging of Karelia in connection with the competition of live native cover, hardwood, undergrowth. In terms of the number of wood and shrub plants on almost all cuttings the first three places are occupied by birch, aspen and undergrowth, and birch quantitatively predominates. The undergrowth is mostly represented by a ripple. The success of the subsequent resumption of pine and spruce on the cuttings of the south-west of Karelia is associated with competition for light and soil resources with herbs (grains), hardwoods and undergrowth. The growth of competing vegetation, primarily birch trees, occurs especially actively in drained habitats with relatively fertile soils (types of woodlands, fresh blueberries and cranberries). According to the original types of forest and the composition of the tree, determining the effective fertility of the soil, it is possible to confidently predict the success of the subsequent natural reforestation of the main rocks on the cuttings. However, in the vast majority of the Karelia forest, the amount of conifers that have followed the resumption is insufficient to form coniferous trees without additional forest activities. In the absence of a pargn of pine and ate pre-resumption sufficient for natural reforestation the amount of adulterous breed is inherent in the following original types of forest: pine white -ness (pine), spruce cranberries moist (spruce; pine), spruce fresh (spruce together with pine). On the cutting of other original types of forest, a combination or artificial reforestation is required, with the logging of care in young people.
